LG Dishwasher Float Sensor Location (Find It Easily)

Have you ever noticed your LG dishwasher not draining or stopping mid-cycle? This might be because the float sensor is stuck or in the wrong place. I had the same issue, and finding the float sensor helped me fix the problem quickly. In this article, I will tell you exactly where the LG dishwasher float sensor is located and how you can check it yourself to keep your dishwasher working well.

Where to Look Inside Your LG Dishwasher for the Float Sensor

The float sensor in your LG dishwasher is usually found inside the dishwasher tub near the bottom. When you open the dishwasher door, look at the bottom part of the dishwasher’s interior.

The float sensor is a small, round or oval plastic piece that moves up and down with the water level. It might be on the side wall or near the drain area. This sensor stops the dishwasher from overfilling with water by telling the machine when to stop filling.

Sometimes, the float sensor is covered with a plastic shield or housing, so you might need to look carefully. You may also see a small arm or tab connected to it that moves when the water rises. The exact spot can vary depending on the LG dishwasher model, but it is almost always near the bottom front or side of the dishwasher tub.

To find it easier, use a flashlight and look for anything that can move when you gently press it. This will most likely be the float or float sensor. If it doesn’t move, it might be stuck or dirty, causing dishwasher problems.

How to Check if the Float Sensor Is Working Properly

After you find the float sensor, you want to make sure it is working right. A stuck or broken float sensor can cause your dishwasher to overflow or stop working. First, try to move the float sensor up and down by hand. It should move freely without any resistance. If it is stuck or feels stuck, it could be dirty or broken.

Next, clean around the float sensor carefully. Sometimes food bits, soap scum, or hard water minerals build up and stop it from moving. Use a soft cloth or a toothbrush and some warm soapy water to clean the area. After cleaning, check if the float sensor moves smoothly again.

You can also check if the float sensor’s switch works using a multimeter if you have one. The float sensor is connected to a switch inside that tells the dishwasher when to stop filling water. If you don’t know how to use a multimeter, it’s best to call a technician. But moving and cleaning the float sensor often fixes the problem.

Test the float sensor by moving it up and down by hand
Clean the float sensor and the area around it with warm soapy water
Check if the float sensor moves smoothly and is not stuck
Use a multimeter to test the float switch if possible
Call a professional if you are unsure or if the problem continues

What Tools You Need to Access and Inspect the Float Sensor

To reach and inspect the float sensor on your LG dishwasher, you will need some simple tools. The float sensor is usually inside the dishwasher, so you don’t need to take the whole machine apart. Start by opening the dishwasher door and pulling out the bottom rack to get clear access to the floor of the dishwasher.

You may want a flashlight to see better inside the dishwasher tub, especially if the light is low. A soft cloth or small brush is helpful for cleaning the sensor and its housing. If you plan to test the float sensor with a multimeter, you will need the multimeter device as well.

Sometimes, to fully inspect or replace the float sensor, you might have to remove the lower dishwasher panel or access the dishwasher’s base from underneath. For this, a screwdriver set (usually Phillips or flathead) will help. It’s good to check your dishwasher manual to see if you need any special tools for your model.

How to Clean and Fix a Stuck Float Sensor in LG Dishwasher

If the float sensor is stuck, it can cause water to keep filling or stop your dishwasher from running correctly. Cleaning the float sensor is often the easiest fix. First, gently lift the float sensor and see if it moves. If it doesn’t, try to remove any dirt or debris blocking it.

Use warm water and mild soap to clean around the float sensor. A toothbrush or soft cloth works well to get rid of grime and buildup. Make sure to clean the float housing or cover too. After cleaning, try to move the float sensor again; it should now move up and down freely.

If cleaning does not fix the problem, check if the float sensor is damaged. Sometimes, the float can crack or the switch inside can fail. If you find damage, you will need to replace the float sensor. You can buy the replacement part online or at a local appliance store. Replacing it is usually simple and does not require expert help.

How to Remove and Replace the Float Sensor in Your LG Dishwasher

If your float sensor is broken or not working after cleaning, replacing it is the best choice. To start, unplug your dishwasher or turn off the power from the breaker to stay safe. Next, open the dishwasher door and remove the bottom rack.

Most LG dishwashers have the float sensor clipped or screwed in place near the bottom of the tub. You may need to remove a small plastic cover or panel to reach it. Use a screwdriver if needed to remove screws. Once you can reach the float sensor, carefully disconnect any wires connected to it. Remember or take a photo of where the wires go for reassembly.

Remove the old float sensor by pulling it out or unscrewing it. Take the new float sensor and connect the wires the same way as before. Put the sensor back in place and secure it with screws or clips. Replace any panels you removed and put the dishwasher rack back in.

Finally, restore power and run a short cycle to check if your dishwasher works well and the float sensor stops the water correctly.

Turn off power or unplug the dishwasher for safety
Remove the bottom rack and access the float sensor area
Remove screws or clips holding the float sensor
Disconnect wires carefully, noting their positions
Replace the old float sensor with the new one and reconnect wires
Secure the new float sensor and reassemble dishwasher parts
Test the dishwasher after replacement

Signs Your LG Dishwasher Float Sensor Needs Attention

Knowing when your LG dishwasher float sensor is having problems can save you time and money. One common sign is that the dishwasher fills with too much water or leaks from the bottom. This means the float sensor is not telling the dishwasher to stop filling.

Another sign is when the dishwasher stops working mid-cycle or does not fill with water at all. This can happen if the float sensor is stuck in the “up” position or the switch inside it is broken. You might also notice the dishwasher making strange noises or taking longer than usual to finish.

If you see water pooling inside or under your dishwasher, or if it won’t drain properly, check the float sensor right away. Ignoring these signs can lead to bigger problems or expensive repairs. Regularly checking and cleaning the float sensor helps your dishwasher run smoothly.

Frequently Asked Questions (FAQs)

Is it easy to find the float sensor in my LG dishwasher?

Yes, it is usually easy to find the float sensor. It is inside the dishwasher near the bottom, often on the side or front wall of the tub. You can open the door and look carefully with a flashlight to see a small plastic piece that moves up and down with water. It may have a plastic cover, but it should still be visible. If you remove the bottom rack, it becomes easier to see. Just remember to be gentle when checking it.

Can a stuck float sensor cause my dishwasher to stop working?

Yes, a stuck float sensor can stop your dishwasher from working properly. The float sensor controls the water level, so if it is stuck in the up position, the dishwasher may think it is already full of water. This can stop the dishwasher from filling or running its cycle. Cleaning the float sensor usually fixes this problem, but if it is damaged, you might need to replace it.

Do I need special tools to check or replace the float sensor?

No, you only need basic tools like a screwdriver and maybe a flashlight. To clean the float sensor, a soft cloth or small brush is enough. If you want to test the sensor’s electrical switch, a multimeter is needed, but it is not required for most people. Always turn off the power before working inside the dishwasher.

Is it safe to clean the float sensor myself?

Yes, it is safe if you follow some simple rules. Always unplug your dishwasher or turn off the power before cleaning. Use gentle soap and water, and a soft brush to clean around the float sensor.
